SHOE-HEATER.

SPEQIFICATION forming part of Letters Patent No. 728,703, dated May 19, 1903.

Application filed July 31, 1902:

To (tZZ whom it may concern:

Be it known that I, MARY C. GElpARD, a citi-,

zen of the United States, residing at Norfolk, in the county of Norfolk, State of Virginia, have invented certain new and useful Improvements in Shoe-HeatersfandI do hereby declare the following'to be a full, clear, and exact description of the invention, such as will enable others skilled inthe' art to which it appertains to make and use the same. This invention relates to shoes, and more particularly to means for heating shoes, the

object of theinvent'ion being to providea shoe that may be worn by a person exposed to low temperatures and which will act to warm the foot without requiring it to be exercised to induce circulation.

A further object of the invention is to provide a construction in which a cheap andcon venierit heating medium may be-employed and in which the ashes will be held until it is desired to empty them.

Other objects and advantage'sof the invention will beunderstood from the following description. f

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar-parts in both views,

perspective siew showing the Figure 1 is-"a Fig.

shoe embodying the present-invention;

2 is a vertical section taken longitudinally through the shoe. 7 I

Referring now to the drawings, there is shown a shoe comprising the upper 5 audiosole 6, having the usual form and assembled in the usual manner, the upper and insole being made of whatever'material or mate- I rials may be deemed most advisable to suit 5o 12 of leather. At the the conditions of use ofthe shoe.- The sole of the shoe comprises an upper metal plate 7 and a lower metal plate 8, which is spaced therefrom,'and whichplates are connected by the wall 9, the with the-Wall against the upper face of the lower plate 8 and against the edge of the upper-plate 7. The bottom plate 8 beyond the .wall is turned upwardly to form the head 10, between which and the wall 9 is engaged the asbestos strip 11, having an exterior facing toe of the shoe is an opening13, provided with a sliding door 14, the lower edge of which engages behind the plates and wall beingsoldered" Serial No. 117,742. (No modelv) wardly and then downwardly and under the laterally-turned p0rtion15 of the upper edge of the wall9, that'projects above the upper plate 7,.so that the closure may be slid into and out of position over the opening. This closure has perforations 116 'th'erethrough to permit of a draft. Upon the upper face .of the laterally extendingportion of the plate 7 is a layer 17 ofasbestos'and' a layer 18',of leather, so that the exterior of the sole has a ,leather' covering which gives it very much the appearance of the ordinary-leather sole. Through the wall 9, adjacent to'the upper edge thereof, are perforations l9, which are continued through the asbestos and leather coveringsand permit access oLair to the-interior of the, sole .to support combustion of thepunk 20, which is employed asa fuel. To prevent the ashes of the punk from blowing out through the perforations, foraminous coverings 21 are secured against the inner face 'of the wall over the perforations or openings, this imateri'al being of, coarse cloth or any other style ofscreening.

i To facilitate the draft through the shoe to insure proper combustion, a flat pipe 22 may be provided, leading from the upper portion of the wall 9 at'lthe rear of the heel upwardly and against the counter of the shoe, thispipe h'avinga coveringof leatheror suit able enamel to renderit inconspicuous.

- In practice when the shoe is to be heated .theslide/is drawnas. shown in Fig.1 and oneend of the .piece of punk is-lighted and moved to closed. position. 'I,he combustion of the punk is very'slow, so that it lasts a ture of the shoe above blood heat, there being enough air permitted to enter through the perforations in the sole and in the slide to support combustion. When the punk is con:

shoe-sole andanother piece of punk inserted, it being understood that if the heat is to be increased more than one piece of punk may be lighted or a single piece maybe lighted at both ends. a

It will be understood that in practice modifications of the specific construction shown long while and does not raise.'the tempera,

may be made and that any suitable materials passed into the sole, afterwhich the slide is sumed, the ashes may be emptied from the IOO invention.

ing in the space between the portion of the connecting-Wall belowthe opening and the upwardly-t nrned portion of the lower spaced plate and'a' flue leeding'from the rear of the lf10u10W sole to facilitate combustion of the ue. 2. The shoe thecombination-with a hollow sole-having upper and lower spaced plates having a connecting-wall at their edges and provided with ventilating openings and n second opening to permitof "the insertion of fuel,"of a. closure forthe second opening and a fine connected withthefrear of .the'hollow .sole to facilitate combustion of the fuel.
